You can retrieve the email body in Office Mailbox API version 1.1 and above by calling the Office.context.mailbox.getCallbackTokenAsync method and making an ajax call to an EWS server. The example Microsoft provides is located at this link:

https://learn.microsoft.com/en-us/javascript/api/outlook/office.mailbox?view=outlook-js-1.1#getcallbacktokenasync-callback--usercontext-

My working example:

Office.context.mailbox.getCallbackTokenAsync({ isRest: true }, (result) => {
    var ewsId = Office.context.mailbox.item.itemId;
    var token = result.value;

    // var restId = Office.context.mailbox.convertToRestId(ewsId, Office.MailboxEnums.RestVersion.v2_0); this does not work on API version 1.1
    var restId = ewsId.replaceAll("/", "-").replaceAll("+", "_"); // Convert ewsId to restId
    var getMessageUrl = (Office.context.mailbox.restUrl || 'https://outlook.office365.com/api') + '/v2.0/me/messages/' + restId;
    var xhr = new XMLHttpRequest();
    xhr.open('GET', getMessageUrl);
    xhr.setRequestHeader('Prefer', 'outlook.body-content-type="html"') // for retrieving body as HTML
    xhr.setRequestHeader("Authorization", "Bearer " + token);
    xhr.onload = (e) => {
      var json = JSON.parse(xhr.responseText);
      var emailBody = json.Body.Content;
    }
    xhr.send();
  });

This is expected. Office.context.mailbox.item.body.getAsync minimum mailbox requirement version is wet to 1.3 level API. In same time according to "Understanding Outlook API requirement sets" the Outlook Web App (Exchange 2013 On-Premise) supports only 1.1 level API.
